Adaptive radiation - the rapid evolution of many new species from a single ancestor - is a major focus in evolutionary biology. Adaptive radiations often show remarkable repeatability where lineages have undergone multiple episodes of adaptive radiation in distant places and at various points in time - implying their extraordinary evolutionary potential.

Tohoku University researchers have improved a method for probing semiconducting crystals with light to detect defects and impurities. The details of their 'omnidirectional photoluminescence (ODPL) spectroscopy' set-up were published in the journal Applied Physics Express, and could help improve the fabrication of materials for electric cars and solar cells.

Researchers from the University of Tsukuba demonstrate that the hypnotic and teratogenic effects of thalidomide are separable. Thalidomide is a medication with several different effects, one of which is promoting sleep in the context of insomnia. In a new study, researchers from the University of Tsukuba have discovered that thalidomide exerts its hypnotic effects through mechanisms distinct from those for the drug’s notorious teratogenicity. These are striking results showing how thalidomide induces sleep independently of its known effects on the teratogenic cereblon pathway. These findings could be helpful in developing novel thalidomide-like hypnotic drugs without thalidomide’s teratogenic effects. The study was published in the scientific journal Proceedings of the National Academy of Sciences of the United States of America.

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of frequent and cataclysmic impacts from asteroids and other bodies. It was thought that this period had a relatively sudden onset, but the researchers have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.
A quantum circuit on quantum computers for a probabilistic spin clean-up/annihilation method
25 Sep 2020
Researchers at Osaka City University create a quantum algorithm that removes spin contaminants while making chemical calculations on quantum computers. This allows for predictions of electronic and molecular behavior with degrees of precision not achievable with classical computers and paves the way for practical quantum computers to become a reality.
Nanosecond pulse laser-induced amplification of a photochemical reaction of diarylethene nanoparticles
25 Sep 2020
An Ehime University group led by Dr. Ishibashi and Prof. Asahi reported that when a nanosecond laser pulse was irradiated to diarylethene nanoparticles which show the photo-induced isomerization reaction from the colored closed-form to the colorless open-form, the ring-opening reaction was at most 80 times more effective than that in the solution phase. The amplification could be well explained as a ‘photosynergetic effect’ coupled with nanoscale photothermal conversion and a photochemical reaction. There are very few reports of such a nanosecond laser pulse induced amplified photochemical reaction in nanoparticles, indicating a new photoenergy conversion method.

Drugs tackling chronic myelogenous leukemia have completely transformed prognoses of patients over the last couple of decades, with most cases going into remission. But drug resistance can occur, leading to relapses. Targeting the lipids involved in regulating part of a leukemia stem cell’s life span offers a potential second route to defeat the disease—and solid tumorous cancers as well.

Three developing stages and OH-PCBs concentration of a Japanese macaque fetus
14 Sep 2020
This study selected the Japanese macaque (Macaca fuscata) as a model animal for the fetal transfer of OH-PCBs in humans, and revealed OH-PCB concentrations and their relationships in the maternal and fetal brains. The key finding from this study is that OH-PCBs can reach the developing brain of the fetus as early as the first trimester of pregnancy. These OH-PCBs may exceed the levels that induce adverse effects on neurodevelopment.
